“…The figure shows a good agreement for the values of Nusselt number, the maximum deviation was within one percent. On the other hand, the values for the average Sherwood number calculated by the computer program are slightly lower than that of Amiri [21]. The results are very close at low Lewis number, but the maximum deviation at higher values of Lewis number was less than five percent.…”

“…3 plots the effect of Lewis number on both the average Nusselt and Sherwood numbers when the outer cylinder was rotating and the rotational Reynolds number was 100. The graph compared the predicted results from the designed program to that given by Amiri [21] for a range of Lewis number from zero to ten. The figure shows a good agreement for the values of Nusselt number, the maximum deviation was within one percent.…”

“…They showed the effect of rotation on the development and merging of the multi-layered flow structure and various field variables. Al-Amiri and Khanafer [21] investigated the laminar flow and heat transfer characteristics of a binary fluid within a two-dimensional horizontal annulus with cooled rotating outer cylinder. They assumed the inner cylinder to be the heated wall and the source for the species concentration.…”

This paper presents the numerical study of mixed convection in a two-sided lid driven porous cavity due to temperature and concentration gradients. The top and bottom walls are stationary and insulated. The left and right walls are moving at an equal velocity (V o ) in the same direction. The temperature and concentration are kept high at the right wall and low at the left wall. The governing equations are discretized using finite volume method. The pressure-velocity coupling is performed by the SIM-PLE algorithm. A third order differed QUICK scheme is applied at the inner nodes and a second order central difference scheme is used at the boundary nodes. The flow behavior and heat transfer are analyzed for different nondimensional numbers, such as, 1 × 10 −4 ≤ Ri ≤ 10, 1 × 10 −4 ≤ Da ≤ 0.1 and 0.7 < Pr < 10. The present numerical results are compared with the literature and are in good agreement. For the above selected nondimensional numbers, the heat and fluid flow behavior is investigated using local and average Nusselt (Nu) and Sherwood (Sh) numbers. Results show that the convection flow is significant up to Da = 0.1, beyond that the effect of porosity is negligible. The effect of Prandtl number (Pr) on average Nu is found to increase significantly. C⃝ 2014 Wiley Periodicals, Inc.
